In the study 30 Accessions of dragon fruit germplasm resources were described and evaluated in terms of its partial agronomic traits and quality traits on the preliminary assessment.Results show that:(1) there are 6 natural flowering precocious germplasm,the proportion is 20％;(2) there are 14 pitaya germplasm resources which Fruit-set rate is over 90％,and the proportion reaches to 46.7％.(3) there are 7 pitaya germplasm resources that the mean fruit weight more than 350 g,and the proportion is 23.3％;(4) There are 14 pitaya germplasm resources,about 46.7％,that edible rate is over 70％.(5) there are 9 pitaya germplasm resources,about 30.0％ of theirs mature fruit which have soluble solid content more than 18％ at the center of flesh,and the highest content is up to 20.3％.There are 46.7％ of pitaya germplasm resources that the average of fruit soluble solid content is more than 15％.According the result above,3 excellent germplasm have been selected from the 30 Accessions of dragon fruit germplasm resources.%针对收集保存的30份火龙果种质资源,对其部分农艺性状和品质性状进行了初步的鉴定评价.结果表明:早熟种质6份,占20.0％;14份座果率达90％以上,占46.7％;7份平均单果重350 g以上,占23.3％;17份可食率达70％以上,占56.7％;9份成熟果实果肉中心可溶性固形物含量达18％以上,占30.0％,最高含量可达20.3％;全果平均可溶性固形物含量大于15％的有14份,所占比例达到46.7％.综合以上特征,初步筛选优级种质(品种)3份.
